Coconut’s triumph over erosion at Currimundi
  • Saturday 01 August 2009

Currimundi Lake Catchment Care Group (CCCG) and council have been working together to tackle erosion at the Currimundi lake using coconut fibre to create a natural retention wall.

The 60 metre retention wall is made from coir logs, a coconut plantation by-product. Coir logs are flexible and can be planted to provide cost effective, long-term erosion control.

Council provided support, site identification, technical advice and labour to the CCCG, who successfully applied for Federal Government funding through the Caring for Country program.

Chris Allan, manager of environmental operations said that the partnership between council and community groups such as the CCCG is invaluable.

“The CCCG identified the Noel Burns Park site as an active erosion spot and were keen to protect the existing trees before they fell into the lake,” Mr Allan said

“The first 30 metre section of the retention wall has done wonders in protecting the banks from flooding over the past two months, and the completion of the additional 30 metre section should help protect the bank for around five years.

“Council’s Community Group support team has been working closely with community groups for a long time now and this partnership is really driving successful environmental outcomes right across the Coast.

“The CCCG will continue to monitor the site, providing crucial data, which can be used for other sites on the Coast,” Mr Allan said.

The Noel Burns Park is a popular area, with a path running alongside the lake. Interpretive signage has been installed onsite detailing project information.

Coir logs are a well recognized erosion control product and fully biodegradable. They are relatively cheap, can be installed without machinery and don't require a lot of technical expertise to install. They can be planted into with fibrous rooted plants such as lomandra species (mat rush) and other sedges which when grown should provide long-term erosion control.
